WordPress MU

Hello,

I have created a page called "Welcome to Wyatt" in WordPress MU
and have set the order number as "0".

However for some reason, my page id is 32. So when I go to my url:
http://eastcoasttechwriter.ca/wordpress/
a blank page displays.

However, when I go to this url:
http://eastcoasttechwriter.ca/wordpress/?page_id=32
my home page is displayed.

How do I fix this?

The the order number as "0" has nothing to do with displaying it as the home page. Nothing at all. It is only used when you are using a template tag to display a list of pages.

If you want that page displayed on the front of the site, go to Settings -> reading. There's options there to pick.
